Leaf-miner:
Rather
narrow, long, corridor, of which the course largely is dictated
by the venation; the mine may change direction (up/down). The larva
may leave its mine and restart elsewhwere. Pupation within the mine;
pupa in a white cocoon, just above the waterline (Bladmineerders van Europa).
Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).
Whitish; head black; pronotum laterally with a black spot (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Adult:
The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk.
Comments:
Hering (1957a) and older authors also mention Phragmites australis
[as a host]; this is not repeated by later authors, and possibly
stems from confusion with other species (Bladmineerders van Europa)
